SIMATIC S7-200 Micro PLC自成一體：:
特別緊湊但是具有驚人的能力－特別是有關(guān)它的實(shí)時(shí)性能－它速度快，功能強(qiáng)大的通訊方案，并且具有操作簡(jiǎn)便的硬件和軟件。但是還有更多特點(diǎn)：
SIMATIC S7-200 Micro PLC具有統(tǒng)一的模塊化設(shè)計(jì)－目前不是很大，但是未來不可*的定制解決方案。這一切都使得SIMATIC S7-200 Micro PLC在一個(gè)緊湊的性能范圍內(nèi)為自動(dòng)化控制提供一個(gè)非常有效和經(jīng)濟(jì)的解決方案。
用于擴(kuò)展通訊選項(xiàng)的2個(gè)內(nèi)置串口，例如：與其它制造商的設(shè)備配套使用（CPU 224 XP, CPU 226）
具有內(nèi)置模擬輸入/輸出的CPU 224 XP
4 個(gè)不同的基本單元 
分級(jí)的性能能力，適用于變化zui大的應(yīng)用 ?CPU 221： 智能緊湊型解決方案
CPU 222： 高級(jí)緊湊型解決方案
CPU 224： 緊湊型高性能 CPU
CPU 226： 用于完成復(fù)雜技術(shù)任務(wù)的高性能組件

SIMATIC S7-200系列PLC適用于各行各業(yè)，各種場(chǎng)合中的檢測(cè)、監(jiān)測(cè)及控制的自動(dòng)化。S7-200系列的強(qiáng)大功能使其無論在獨(dú)立運(yùn)行中，或相連成網(wǎng)絡(luò)皆能實(shí)現(xiàn)復(fù)雜控制功能。因此S7-200系列具有*的性能/價(jià)格比。

　　After the accident, Dad was reluctant to play the mandolin. He felt that he could not play as well as he had before the accident. When I came home on leave and asked him to play he would make excuses for why he couldn't play. Eventually, we would wear him down and he would say "Okay, but remember, I can't hold down on the strings the way I used to" or "Since the accident to this finger I can't play as good". For the family it didn't make any difference that Dad couldn't play as well. We were just glad that he would play. When he played the old mandolin it would carry us back to a cheerful, happier time in our lives. "Davey, Davey Crockett, King of the Wild Frontier", would again be heard in the little town of Bakerton, West Virginia.

　　In August of 1993 my father was diagnosed with inoperable lung cancer. He chose not to receive chemotherapy treatments so that he could live out the rest of his life in dignity. About a week before his death, we asked Dad if he would play the mandolin for us. He made excuses but said "okay". He knew it would probably be the last time he would play for us. He tuned up the old mandolin and played a few notes. When I looked around, there was not a dry eye in the family. We saw before us a quiet humble man with an inner strength that comes from knowing God, and living with him in one's life. Dad would never play the mandolin for us again. We felt at the time that he wouldn't have enough strength to play, and that makes the memory of that day even stronger. Dad was doing something he had done all his life, giving. As sick as he was, he was still pleasing others. Dad sure could play that Mandolin!
